A battery pack that prevents a solder material from flowing down due to a tab electrically connecting a battery to a protective circuit board, thereby improving reliability, coupling efficiency, safety, and productivity is disclosed. The battery pack includes: a multi-cell battery having a positive electrode and a negative electrode, in which a plurality of battery cells are electrically connected to each other; a protective circuit board electrically connected to the multi-cell battery and having via holes; a pair of conductive tabs each including an insert portion inserted into a corresponding via hole and a bending portion integrally extending from the insert portion and bent from the insert portion; and a pair of soldering portions each being formed at at least some portions of a corresponding insert portion and a corresponding bending portion.
